An object of the present invention is to provide a method for manufacturing a workpiece composed of several plate-shaped materials, in which the plate-shaped materials may be the same or different from each other. The workpiece is manufactured to produce the reinforced workpiece in an automatic and reliable manner.

This object is solved by a method of manufacturing a workpiece. In the present method, the first plate-shaped material is placed in the work area of the processing table of the work area and is held so as to be movable by the carrier along the work support in the work area. The at least one second plate-like material is placed in the work area of the workbench and is held movably along the workpiece support in the work area by an additional carrier of the workbench. At least one first workpiece part is manufactured from a first plate-like material. At least one first workpiece part is provided for a second plate-like material placed in the work area, and at least one first workpiece part is this plate-like material or second workpiece. Connected to the part, the second workpiece part is manufactured from the second plate-like material and is at least partially machined. At least one second workpiece part connected to at least one first workpiece part is completed on the processing table. According to the method, for example, the selectable first and second plate-like materials may differ from each other in terms of material thickness and / or material, but both are simultaneously in the same processing table workspace. It is placed and held by a carrier. As a result, for example, at least one first workpiece part is manufactured from one of two plate-like materials, placed on the other plate-like material, and into the other plate-like material. Connect and then manufacture reinforcement work. The second workpiece part is manufactured from the other plate-shaped material. By arranging the workpiece parts from at least one plate-shaped material on the adjacent plate-shaped materials, intermediate storage becomes unnecessary. In fact, rapid continuous machining may be possible. As a result, the cycle time can be reduced.

According to the method according to the invention, several plate-like materials can be placed in the work area, which not only allows the production of workpieces consisting of two different steps and / or layers, but also multi-layer workpieces or Sandwich structures can also be manufactured. It is also devised to manufacture a workpiece from at least two workpiece parts having recesses or grooves to construct a channel or cavity. It is possible to construct a conductor track on an insulating substrate by the method according to the present invention. When using plate-like materials with different properties, for example, at least one step and / or layer of wear resistant material can be placed on the soft substrate.

According to a preferred embodiment of the method, the first and / or second workpiece parts are cut from the plate-like material or from the residual grid resulting in the final machining step of the machining area of the table. Thus, at least one of the two workpiece parts can remain on the second plate-like material, or on the residual grid formed on it by the final machining step or working step, and all. It can move within the workpiece support until the required work steps are performed. Only after this will the reinforcing work piece be separated from the work piece support and moved.

According to a preferred embodiment of the method, the second workpiece is partially completed before at least one first workpiece is placed on it. Alternatively, it is completed except for at least one connecting bridge to the residual grid of the second plate-like material. As a result, optimum processing is possible. Specifically, perforated portions, embossing, recesses or deformations can also be introduced into the second workpiece component. Drilling portions, embossing, recesses or deformations cannot be introduced after at least one first workpiece part has been placed relative to the second workpiece part.

According to a more preferred embodiment of the method, at least one first workpiece component is lifted by a tool from the plane of the workpiece support and placed so as to overlap on the second plate-like material, concretely. It is arranged so as to overlap at least the second partially processed workpiece part of the second plate-shaped material. As a result, traversing or elevating shafts are used in the machining table to traverse at least one first workpiece part with respect to the second plate-like material, thereby simplifying the tooling of the machining table. You will be able to control it.

In addition, a drilling tool is used to process at least one workpiece part and place it relative to the second plate-like material. Such a drilling tool allows the first workpiece part to be separated from the residual grid of the first plate-like material at the same time as the separation tool, specifically tightening or wedge fixing using drilling. Will be. This eliminates the need to change the tool, but rather the drilling tool allows cutting and processing to be performed simultaneously, placing the first workpiece on the second workpiece. be able to. Alternatively, after cutting the first workpiece part from the residual grid of the first plate-like material, the second workpiece part can be mounted by a processing device such as, for example, a suction carrier. Further, in order to shorten the processing time, several first workpiece parts can be simultaneously supported by a suction carrier and arranged on the second plate-shaped material.

Further, the holding bracket or holding frame is formed on at least one first workpiece part for processing. The holding bracket or holding frame is separated after the first workpiece part is connected to the second plate-like material. These additional holding brackets or frames are selected, especially for parts that are small, difficult to process, and whose surface is not suitable for suction-supporting elements of suction-supporting devices.

According to a more preferred embodiment of the method, at least one placement aid after placing the first work piece with respect to the second, at least partially machined work piece or second plate-like material. Is introduced into at least one first and / or second work piece. As a result, when the first workpiece part is placed relative to the second workpiece part, self-alignment and centering are possible. Such placement aids can be implemented, for example, by holes and centered studs or centered nipples. Embossing and complementary recesses can also be formed.

The at least one first workpiece part or the second at least partially machined workpiece part is specifically tightened or glued, soldered, welded or mechanically locked by means of joining without the use of additional materials. , Can be connected to each other. The selected connection depends on the selected material and / or thickness or thickness ratio of at least one first workpiece part and second workpiece part.

By a more advantageous embodiment of the method, several first workpiece parts of the first plate-like material are at least partially completed and of the first workpiece part of the first plate-like material. A plurality of second workpiece parts corresponding to the number are at least partially machined with a second plate-like material, and the first and second workpiece parts are each residual grid or plate-like. The first and second plate-like materials, which are held by connecting bridges in the material and have the first and second workpiece parts, are placed simultaneously with each other. Specifically, the processing time can be further shortened during the production of a large number of the same reinforcing workpieces. The first work piece is not individually placed with respect to the second work part, but rather a plurality of first work parts are with respect to the second work part made of all plate-like materials. Are placed at the same time.

According to the above-mentioned first embodiment of the present method, the first plate-shaped material can be lifted and arranged so as to overlap the second plate-shaped material. Alternatively, the first plate-like material can be placed by folding onto the second plate-like material. Depending on which of the two placement stages is selected, the shape of the workpiece must be aligned with the plate-like material accordingly.

Further, the first and at least one second plate-like material is preferably machined on a processing table by at least one drilling tool and / or bending tool and / or laser cutting. The workpiece processing machine is preferably designed as a so-called drilling and compound machine. This machine allows for both drilling and laser cutting. Individual bending treatments may also be performed, if applicable.

In a more preferred embodiment of the method, the reinforcing workpiece has two parts and is manufactured from a plate-like material and connecting parts. For example, the connecting part may be a threaded insert, or a threaded sleeve or another connecting element so that the sheet metal part and another part can be securely fastened.

Preferred embodiments are also considered as follows. In this embodiment, the reinforcing workpiece is formed from at least two plate-shaped materials by the means of the present method. At least two plate-like materials have the same and / or different thicknesses, materials and dimensions, and recesses such as holes, elongated holes and threads or passages are introduced into workpieces reinforced with plate-like materials. To.

In addition, the method can be used to manufacture reinforcing workpieces as an assembly of several, in particular, different materials. For example, it is possible to manufacture a surface component that has a high quality surface on the one hand and is connected to an internal support component on the other hand.

Further, this method can be used to manufacture a multi-layered workpiece. For example, structured sandwich panels with hardened ribs or hardened contours can be manufactured. In this method, materials can be used, for example, depending on requirements such as appearance, strength, and weather resistance.

FIG. 1 is a perspective view of a workpiece processing machine 11 for processing plate-shaped materials 12 and 13, such as a metal plate. Here, such plate-shaped materials 12 and 13 include drilling, bending, display embossing, engraving, chamfering, roll forming, particularly roll pinching, thread formation and film film on the surface of the plate-shaped material. May include separation. Further, the workpiece processing machine 11 enables further cutting processing using a laser. The workpiece processing machine 11 has a C-shaped support frame 14. The C-shaped support frame 14 has a leg portion 15 of the upper frame and a leg portion 16 of the lower frame. The conventional adjustment guide 17 is housed in a thick region between the legs 15 of the upper frame and the legs 16 of the lower frame. Thereby, the plate-shaped workpieces 12 and 13 can be arranged or moved with respect to the processing table 18 of the workpiece processing machine 11, and the tool 20 can be stored, changed and replaced on the processing table 18.

The tool 20 is replaced on the processing table 18. The tool 20 includes an upper tool 21 and a lower tool 22. The lower tool 22 is arranged on the workbench 25 in the lower tool receiving portion 23. The workbench 25 is located on one side of the lower support frame 16 of the machine frame 14. The upper tool 21 is attached to the upper tool receiving portion 24 of the pusher 26. The upper tool 21 can be moved up and down by water pressure, for example, can be moved up and down in the direction of the double-headed arrow 27 on the leg portion 15 of the upper frame of the frame 14. Both the upper tool 21 and the lower tool 22 are adjustable or feedable around the elevating shaft 28 of the pusher 26 in the direction of the double-headed arrow 29. The corresponding feed motion is also controlled using the control device 30 of the generally illustrated workpiece 11 as well as other basic mechanical functions. The work area 37 of the workbench 18 is formed by at least one workpiece support 38 of the workbench 25, and at least one first plate-like material 12 is held by the carrier 32 during machining by the tool 20. It is guided to the processing table 18 in a movable manner. Further, at least one other plate-like material or a second plate-like material 13 is held in the working area 37 by using another carrier 39. The carrier 39 advantageously corresponds to the carrier 32. These two supporting devices 32, 39 are preferably controlled independently of each other in order to move the first plate-shaped material 12 and the second plate-shaped material 13 on the workpiece support 28. .. Alternatively, another plate-like material can be placed and accepted in the work area 37 by another carrier.

The first plate-shaped material 12 is advantageously different from the second plate-shaped material 13. This difference may be due to the thickness of the plate-like material, the choice of material and / or the surface. After the reinforcement work 34 is completed from the first plate-like material and at least one additional material, specifically the second plate-like material, the reinforcement work 34 may provide, for example, the base portion 35 of the workbench 25. By lowering it, it is guided to the outside from the processing table 18. This embodiment will be described in detail below.

2 to 8 show a continuous working stage in which the workpiece processing machine 11 according to FIG. 1 is provided and the reinforcing workpiece 34 is manufactured. In a typical embodiment of the following reinforcing work 34, for example, in a thickened or reinforcing sheet metal portion, a reinforcing layer is provided in a region for hardening and / or a region for absorbing a large amount of force. There is.

FIG. 2 shows a schematic view from the upper part of the work area 37 of the processing table 18. In the figure, the first plate-shaped material 12 is lifted by the carrier 32, and the second plate-shaped material 13 is lifted by another carrier 39. The second plate-shaped material 13 may be the same as the first plate-shaped material 12, and is preferably different. In the first working stage, the first and second plate-like materials 12, 13 are processed together or individually. In the first plate-like material 12, the first workpiece part 41 is manufactured and placed completely separate from the residual grid 42, or a residual grid with at least one connecting bridge not shown in detail. It is fixed and held at 42. In the second plate-shaped material 13, the processing of the second processed workpiece part 44 is also performed. This process may be carried out only partially or completely. Thereby, the second workpiece part 44 continues to be connected only to the resulting residual grid 45 through at least one connecting bridge.

FIG. 2 shows that several identical first workpiece parts 41 and several identical second workpiece parts 44 are formed. This formation is carried out, for example, in the continuous production of parts. However, the individual first and second workpiece parts 41 and 44 can also be manufactured in each case.

If the connecting bridge is still present, the machined work piece 41 is separated from the residual grid 42. Then, according to the arrow 46 in FIG. 2, the work piece 41 is lifted from the work support and placed with respect to the second work part 44. This state is shown in FIG. Although not shown in detail, a suction carrier, specifically a suction gripper or a vacuum gripper, may be placed to process the first workpiece part 41. Alternatively, a drilling tool may be provided. The drilling tool, on the one hand, separates the connecting bridge between the first workpiece 41 and the residual grid 42 and at the same time engages with the drilling contour introduced into the first workpiece 41 and second. Held in a tightened or stretched fashion to perform a transverse movement towards the workpiece 44 of. The first workpiece part 41 can also be held so as to be clamped into a recess in the upper or lower portion of the drilling tool for transverse movement. It is also devised to place the second work piece 44 below the lifted first work part 41.

FIG. 4 shows an enlarged top view of the first workpiece part 41 as an example. The first workpiece component 41 has a placement aid 48. For example, the placement aid 48 may be an engaging hole introduced at the drilling stage. Further, the embossed 49 having a raised or recessed shape may be introduced into the first workpiece part 41. Thereby, the placement aid 48 may simultaneously make an active connection to another work piece 44.

FIG. 5 shows a schematic view of a second workpiece part 44 separated from the plate-shaped material 13 using the separation cut portion 51, except for the connecting bridge 52. The placement aid 48 is introduced in close proximity to the second work piece 44. The placement assist 48 is adjusted with respect to the placement aid 48 of the first workpiece part 41. In this example, the placement aid 48 on the second plate-like material 13 is formed as an engaging stud or ridge to engage with the engaging hole of the first workpiece 41. An additional or alternative hole punching portion 53 may be provided. Thereby, the embossed 49 of the first workpiece 41 can also be engaged to form a positive connection.

In FIG. 6, the first workpiece component 41 is arranged so as to overlap the second workpiece component 44. The positive connection is feasible with the placement aid 48 and / or the embossing 49 and the drilling portion 53 for aligning the two parts with each other. For example, the positive connection is formed by a placement aid 48 on the outside of the stiffener 34. That is, a positive connection is formed between the residual grid 45 and the first work piece 41.

With respect to the embossed 49 and the drilled portion 53, a positive connection is alternative formed between the first workpiece part 41 and the second workpiece part 44.

One or a plurality of connection points 55 may be provided to connect the connection first workpiece component 41 and the second workpiece component 44. Friction connections, critical connections and / or positive connections may be established. Weld points or protrusions or similarities may be provided. As a result, the first workpiece part 41 is fixedly connected to the second workpiece part 44. The composite material of such parts can then be continuously machined. Such subsequent machining will be described in detail below with reference to FIG.

For example, the disconnection may occur in the area of the positive connection between the emboss 49 and the drilling portion 53. For example, another recess 57 that is introduced into both the first workpiece component 41 and the second workpiece component 44 can be introduced. Further, for example, the end portion 58 can be folded along the bending line 59, for example, by 90 °. Deformation and bending of the first and second workpiece parts 41, 44 may also occur in overlapping regions.

After the subsequent machining of the first and second workpiece parts 41, 44 or the composite material of the part is completed, the composite material of the part can be cut. In the first stage, the connecting bridge 52 can be separated. Further, the region 61 of the residual grid 45 can be separated. The composite material of the component then continues to be held while being actively connected to the residual grid 45 using the placement aid 48. The composite material of this component can be removed using a carrier. The composite material of this component can also be completed, for example, by another drilling process shown in FIG. In this drilling process, for example, the placement aid 48 is separated for positive connection because it is no longer needed. In this way, the machined workpiece 34 is completely separated from the residual grid 45. As shown in FIG. 7, instead of partially separating the region 61 of the residual grid 45, the reinforcing component 34 can also be completed immediately by separating the flap portion 50 with the placement aid 48.

The reinforcing work piece 34 is manufactured by using the above method. For example, the reinforcing workpiece 34 is formed rigidly in the intermediate region and has, for example, a cover or folded portion in a corner region that cannot be equipped.

An alternative embodiment of the method described above is also an alternative embodiment of the same number of first workpiece parts, instead of a single process of placing the first workpiece part 41 relative to the second workpiece part 44. 41 is introduced into the plate-shaped material 12, the same number of second workpiece parts 44 are introduced into the second plate-shaped material 13, and the first plate-shaped material 12 is introduced into the second plate-shaped material 12. By folding over 13, all first workpiece parts 41 can be placed simultaneously with respect to the second workpiece part 44. Instead of folding, the first plate-shaped material 12 can also be raised and placed on top of the second plate-shaped material 13 to lower it. In both cases, the placement aid 48 allows the two plate-shaped materials 12, 13 to be aligned. Next, another work step described with reference to FIGS. 6-8 can be performed.

FIG. 9 schematically shows first and second workpiece parts 41, 44 before being connected to the machined workpiece 34 according to FIG. 10 or FIG. This embodiment shows a sheet metal portion having a threaded nut and to which the nut is attached. First, the plate-shaped material 13 is punched out, but only a part thereof is shown. To manufacture the connecting element, the sleeve is drilled or laser cut from the thick plate-like material 12 as the first workpiece part 41. Next, the first workpiece component 41 is arranged together with the processing device with respect to the plate-shaped material 13. The processing device comprises, for example, a pre-drilled hole. Next, the first workpiece part 41 is connected to the second workpiece part 44, for example, by welding. Here, the second workpiece part 44 can be completed or drilled by a laser beam.

FIG. 11 shows an alternative embodiment of the machined workpiece 34 of FIG. In this way, it is possible to provide a compression connection between the first workpiece component 41 and the second workpiece component 44. Alternatively, only one recess is introduced into the hole region of the second plate-like material 13 to realize a defined receptacle for the first workpiece part 41. The first workpiece part 41 can be reconnected to the second workpiece part 44 by gluing, welding or soldering.

In both examples of the reinforcing workpiece 34 of FIGS. 10 and 11, for example, threads may be introduced into the first workpiece 41 before and after the connection of the two workpieces 41, 44. Alternatively, as in FIGS. 9 and 10 or FIGS. 9 and 11, after joining the first and second workpiece parts 41, 44, for example, an insertion portion made of another material is further added to the workpiece part 41. It can be introduced into at least one hole of 44. Such an insertion portion can be manufactured, for example, in a working area comprising a third plate-like material.

12 and 13 show another alternative embodiment for manufacturing the reinforcing workpiece 34. This is, for example, a multi-layered counterbore. In the first workpiece 41, for example, the ring is drilled using the hole 65 and the placement aid 48. The second work piece 44 includes a central hole 66 and a placement aid 48. The placement aid 48 is formed as a ridge, stud or similar. With the placement aid 48, the first work piece 41 can be placed with respect to the second work piece 44, and after alignment, for example, at least two connection points 55 can be introduced. The connection point 55 can also be located directly within the placement aid 48, especially when a welded connection is selected. The two stacked workpiece parts 41, 44 form a stepped hole.

FIG. 14 provides an application example for processing the first or second workpiece parts 41, 44. The first or second workpiece parts 41, 44 cannot be supported by the suction carrier due to the size and / or structure and / or contour of the workpiece. Further, the first or second workpiece parts 41 and 44 cannot be supported by the hole punching processing tool. Within the drilling tool, workpiece parts 41, 44 are held onto the perforator by tightening or stretching. In such cases, the holding bracket 68 can be formed on the first or second workpiece parts 41, 44. The holding bracket 68 is a suitable receiving surface for the suction carrier. The holding bracket 68 is then separable after the first work piece 41 is connected to the second work part 44, similar to the subsequent machining of the composite material of the parts shown in FIG. 7.
